    For Sale: Fortune 100ah cells, Overkill Solar 24v BMS (Seattle)

    Did this sell? I'm in Portland, could meet you just south of Seattle.

    Connecting different amp hours in parallel

    Ok, makes sense. Also seems to be a better idea to repurpose the 60AH (since it's such a large power diff) to a different project and focus on the 280AH for the main house system.

    Connecting different amp hours in parallel

    @FilterGuy if I have a 16S 60AH with a 100a BMS, and a 16s 280AH with a 100a BMS, does that mean I have 200a draw and 340AH total? Thank you for being patient while I struggle with the basics.

    Connecting different amp hours in parallel

    Ok! That makes sense. I doubt you miscommunicated, I probably misheard. So in that case I'm going to switch to a Daly BMS because these batteries will never arrive on a second order.

    Connecting different amp hours in parallel

    @FilterGuy First battery is 16S 48v 60ah Fortune Cells. Second battery is 2x 8s24v in series with 280AH Lishen Cells. I'm doing 2x 8S to get to 200 amps using overkill BMS (we chatted briefly on my other thread) Follow up question. If one bank can do 200 amps, and the other can only do 100...

    Connecting different amp hours in parallel

    Hi! I tried to research this. But I came across a lot of conflicting information. I built my first battery, a 60AH 48v Fortune bank w/ 100amp Overkill BMS. I'm going to build my second battery when parts arrive (if they arrive) 280AH 48v Lishen w/ 2x 8s Overkill BMS (increase the amps)...

    Building a house battery backup

    @FilterGuy I don't know how I'm just now seeing all those incredibly useful links in your sig. Going to be doing some reading tonight!

    Socket head dropped and sparked, is this a short?

    I am such a newbie, and still learning a lot of my math and basic concepts (I learn the fastest by going straight for the deep end). How would I be able to calculate that?

    Socket head dropped and sparked, is this a short?

    Take a look at my screenshot of the BMS. I had just top balanced to 3.6v, the two affected cells are now at 3.3v

    Building a house battery backup

    @wattmatters sounds like I should just drop the water heater, it doesn't really make sense to use it. I am using a 50gal Rheem Hybrid water heater, and now that I'm looking at the spec sheet it's ludicrous to even try keeping it going. It's 4500 watts...

    Building a house battery backup

    @FilterGuy thank you, amazing advice. I just built a 16S pack with the 60AH Fortune cells (was getting tired of waiting for my Chinese cells that are no doubt stuck in a port somewhere). I wanted to combine this with my 240AH cells that are coming, but I used my Overkill 48v on this pack. For...
